The big townships filled in late. Half the houses in Franklin Township and Hillsborough went up in 1986 or later, half in Bernards Township in 1987 or later, and in Montgomery 33 percent of all homes are newer than the 1990s. A house from the late 1980s or the 1990s can still be under the roof it was built with, and shingles that old are often close to worn out. With a first roof there is one layer to strip, and the open question is the deck, which nobody has seen since the house was framed.
The river towns are a different job. Manville's median house dates to 1956 and North Plainfield's to 1954. On a house that age, an earlier crew may have shingled right over the old roof, and the deck underneath can be planks rather than sheets. We count the layers before we price anything.
About 15 percent of county homes are townhouses or other attached houses, and in Bedminster it is 41 percent. A new roof on an attached house goes through the town's construction office, and in many developments the association owns the roof, so the board makes the call.
So the price comes after we have been on the roof. We go up when it is safe to, look in the attic, and find out which kind of roof you have.
